We use natural Japanese oak that is a favorite of stag beetles and rhinoceros beetles. Made in Kagoshima Prefecture. The materials are mainly sourced from mountain forests where rhinoceros beetles and stag beetles can be collected. Thank you for viewing. The product is unprocessed except for cutting. Please check the condition in the photos. The product condition is new and unused, but please understand that we cannot accept claims regarding any dirt or other marks due to the natural wood. [Notes] Due to the nature of the wood, there may be bark peeling, drying cracks, and insect bite marks. Returns and exchanges are not possible to prevent any trouble. Please purchase only after you are satisfied. #JapaneseOak #Oak #ClimbingWood #Ivy #RhinocerosBeetle #StagBeetle #Gecko #Hollow #BeetleTerrarium #BeetleAquarium #Kunu
